Dr. Ann McKee and her team at the VA-BU-CLF Brain Bank have diagnosed four former junior hockey players with chronic traumatic encephalopathy (CTE) in the past two years. None of the four players advanced to the National Hockey League and all died before the age of 30.

“We are focusing on hockey now,” Dr. McKee said in an interview with TSN. “We’re really trying to put together our experience… We’re hoping hockey is not as high a risk as football where there are more impacts every game in a more predictable fashion, but [CTE prevalence] could be just as high in hockey.”
